Inflation Rate
Definition
The inflation rate is the percentage change in the price level of goods and services over a specific period, typically measured annually.
Explanation
Central banks aim for a 2% inflation rate as ideal for economic growth. High inflation above 5% can harm the economy, while hyperinflation (50%+ monthly) destroys currency value. Inflation below 0% (deflation) can lead to economic stagnation.
Understanding the inflation rate helps in financial planning, especially for setting retirement savings targets and investment return expectations.
Example
With an average annual inflation rate of 3.3% over 20 years, prices more than double, making a $50 restaurant meal cost over $100.
